The updated iPad application has been highlighted by several publications a few weeks ago, but it wasn’t available so it didn’t make much sense posting it.

It does make sense now, so here goes!

On Readmill, readers can then discuss, highlight, recommend and share the works with other users, either within the Readmill community or across their social networking services of choice.

In addition to the upgraded iPad app, Readmill is today also announcing new partnerships with six independent bookstores, which have integrated the ‘Send to Readmill’ button at their online checkouts. They include Efendi Books, Ultima, Ellibs, Ebookmall, Feedbooks, Lybrary and Hacker Monthly, extending the total number of supporting retailers to 30 – and counting.

Readmill just raised an undisclosed amount of funding in a Series A round from Wellington Partners. It earlier raised seed funding from Index Ventures and Passion capital, as well as angel investors luke Alexander Ljung and Eric Wahlforss (founders of SoundCloud) and Henrik Werdelin.

The startup was founded by Henrik Berggren and David Kjelkerud in December 2010 and officially launched in December 2011.
